Content

The configuration of the peer content depends on the peer ID type.

 

Do the following when you set Authentication Key to Pre-shared Key.

 

For IP, type the IP address of the computer with which you will make the VPN

 

connection. If you configure this field to 0.0.0.0 or leave it blank, the ZyWALL will

 

use the address in the Primary Remote Gateway field (refer to the Primary

 

Remote Gateway field description).

 

For DNS or E-mail, type a domain name or e-mail address by which to identify

 

the remote IPSec router. Use up to 31 ASCII characters including spaces,

 

although trailing spaces are truncated. The domain name or e-mail address is for

 

identification purposes only and can be any string.

 

It is recommended that you type an IP address other than 0.0.0.0 or use the DNS

 

or E-mailID type in the following situations:

 

1. When there is a NAT router between the two IPSec routers.

 

2. When you want the ZyWALL to distinguish between VPN connection requests

 

that come in from remote IPSec routers with dynamic WAN IP addresses.

 

Do the following when you set Authentication Key to Certificate.

 

1. For IP, type the IP address from the subject alternative name field of the

 

certificate the remote IPSec router will use for this VPN connection. If you

 

configure this field to 0.0.0.0 or leave it blank, the ZyWALL will use the address in

 

the Primary Remote Gateway field (refer to the Primary Remote Gateway field

 

description).

 

2. For DNS or E-mail, type the domain name or e-mail address from the subject

 

alternative name field of the certificate the remote IPSec router will use for this

 

VPN connection.

 

3. For Subject Name, type the subject name of the certificate the remote IPSec

 

router will use for this VPN connection. Use up to255 ASCII characters including

 

spaces.

 

4. For Any, the peer Content field is not available.

 

5. Regardless of how you configure the ID Type and Content fields, two active

 

IPSec SAs cannot have both the local and remote IP address ranges overlap

 

between rules.
